Description

Eyes for the sky!

The Zhumell Telescope 1.25 Inch Eyepiece and Filter Kit is a great way to make the most of your telescope! Zhumell kits include a selection of eyepieces and filters that optimize available light. This, in turn, allows planetary features, galaxies, and binary systems to stand out in fine detail. All kits include fully-coated 1.25 Super Plossl eyepieces to ensure image clarity.

The Zhumell Telescope 1.25 Inch Eyepiece and Filter Kit is the perfect accessory for any scope!

The Zhumell Astronomical Filters attach to the telescope side of the eyepiece barrels. These filters will attach to any astronomical eyepiece with standard threading at the end of the barrel. To use a filter, remove the eyepiece on which you would like to use the filter. Looking at the end of the eyepiece which is inserted into the telescopes eyepiece receptacle, screw the desired filter clockwise into the eyepiece barrel. To remove the filter, turn the filter counterclockwise. Once the desired filter is attached to the eyepiece, insert the eyepiece into the telescopes eyepiece receptacle.

Some notes on Astronomial Filters

Astronomical filters work by blocking out certain colors in the visible spectrum of light. A red filter, for example, will block out all but the red wavelength of light. If you look at an object which is primarily red while using a red filter, the object will appear very bright. Areas which are not red will appear more clearly because they contrast with the wavelength of light which is being passed by the filter.

When using filters, make note of the visible light transmission (VLT) of the filter you would like to use. The VLT is a number which describes the overall amount of light which is allowed to pass through the filter. The lower the VLT number, the dimmer an image will appear. Filters with a VLT less than 40% are not recommended for use on telescopes with an aperture of less than 6" due to the decreased image brightness.

Filters are sorted by the Kodak Wratten numbering system. Each filter is listed by its color and Wratten number. The Wratten numbers help to ensure similar results between different filters. The image should appear the same when viewed through any #82A Light Blue Filter for example.

#12 Yellow - 74% VLT

Yellow Filters help greatly in viewing Mars by bringing out the polar ice caps, enhancing blue clouds in the atmosphere, increasing contrast, and brightening desert regions. Yellow also enhances red and orange features on Jupiter and Saturn and darkens the blue festoons near Jupiter's equator.

#21 Orange - 46% VLT

An orange filter helps increase contrast between light and dark areas, penetrates clouds, and assists in detecting dust storms on Mars. Orange also helps to bring out the Great Red Spot and sharpen contrast on Jupiter.

#23A Light Red - 25% VLT

Light red filters help to make Mercury and Venus stand out from the blue sky when viewed during the day. Used in large telescopes, light red sharpens boundaries and increases contrast on Mars, sharpens belt contrast on Jupiter, and brings out surface detail on Saturn.

#56 Light Green - 53% VLT

Light green enhances frost patches, surface fogs, and polar projections on Mars, the ring system on Saturn, belts on Jupiter and works as a great general purpose filter when viewing the Moon.

#82A Light Blue - 73% VLT

Light blue functions much the same as #80A Blue while maintaining overall image brightness. Light blue will also help to increase structure detail when looking at galaxies.

Polarizing Filter

Polarizing filters are a great way to enhance astronomical viewing. Compatible with any standard 1.25 inch format eyepiece, this filter will help to bring out contrast and definition in astronomical objects. The polarizing filter reduces glare and is especially useful for viewing the moon.

CrystalView Moon Filter

A specific filter for lunar surface viewing. The Moon can be so overwhelming to look at that much of the surface detail is washed away in light. This filter dramatically increases the contrast and detail of the lunar surface.

The lens/filters bundled in this package are great beginers set. Do not expect to slap on a filter and bingo there it is. Planetary filters are designed for large apeture scopes of 6inches...Read complete review

The lens/filters bundled in this package are great beginers set. Do not expect to slap on a filter and bingo there it is. Planetary filters are designed for large apeture scopes of 6inches or better these are in my opinion lunar filters with the ocassional planetary observation.

What you will see with these filters with an 8+ in scope,I have the celestron 8se, nothern and southern bands on jupiter, mars on a great visual night will reward you with polar caps. saturn increased bands. thats it.95% of my filters are used for lunar viewing. Even with a small apeture scope, 4in Celestron PowerSeeker 127 EQ Telescope, the moon is a great visual sight. slap a filter on to cut down on the glare and its fun for the family.

In short do not expect to purchase any filter set and be knocked off your feet. These filters will cut the glare of the moon and enhance to a small degree planetary viewing.

I must say that there are no negative reviews at all about this product, and that is kind of why I was mislead into buying it. Overall I was a bit disappointed after testing out all of the items over several nights. I own a Meade lx90 8" SCT. The scope only had one meade 4000 series 26mm super plossl that came with it. That is why I decided to buy this set to see which magnifications would work well on this long f/10 telescope. It is said that telescopes like mine, which are 8" in aperture or more, and have long focal ratios are much more forgiving when it comes to bad eyepieces.I expected these eyepieces to be at least as good if not better than the meade 4000 series that came with my telescope. I was dead wrong. You are definitely getting your [$] dollars worth here...and it shows. NOTICE!! Look at the description for this eyepiece and filter kit. Don't you think it is odd that there is no specifications? They did not mention how many elements these eyepieces are made of, no mention of how many groups or what kind of glass is used. Even stranger...there is absolutely no mention of the Field of view of these eyepieces. I thought that was rather odd because no other eyepieces on this website that I have seen chose to NOT show such important information. Perhaps they did not write the specifications because they are now considered low by industry standards? They are advertised as "high-grade" but what does this mean? If these eyepieces are indeed high grade why not show us the specifications?ALSO NOTE!! this product is advertised as: 4mm, 6mm, 12.5mm, and 32mm High-grade Plossl eyepieces; 2x Achromatic Barlow. THIS IS NOT WHAT THEY SEND YOU!! In reality, you get one 3.6mm, one 6.3mm, 12.5mm, and 32mm. 32mm: This is the lowest magnification piece in this kit and it performs just fine I think. Again, no one knows what the field of view is because the company decided not to share that information with the buyers. 12.5mm: Seemed alright to me; only issue I saw was that the objects did not come into as sharp focus as they did on my meade 4000 26mm super plossl. Picture was not a sharp, and at the edge some things were blurry. 6.3mm: OK here is where things start getting horribly wrong. My telescope has a maximum useful magnification of 600-680x, so it is never an issue of too high magnification. Looking at Jupiter with this eyepiece, I noticed a dramatic decrease in brightness. Also, the resolution of the image and the quality was a huge drop from the 12.5mm, and even a bigger drop from my 26mm meade 4000. I am very dissapointed in this eyepiece. Looking at stars, even directly overhead showed some strong ghosting and flaring...possibly due to the low quality of the eyepieces, trying to handle a high magnification. The eyehole is a bit small but still manageable if you dont mind sticking your eye onto the eyepiece itself. 3.6mm: Alright, this eyepiece is completely useless. NOONE will ever use this. Not a single telescope owner, who spend a high amount of money to be able to use these magnifications on a large aperture telescope, would be caught dead trying to stick this into their eyepiece holder.- This eyepiece has all of the problem of the 6.3mm in this kit, only doubled and tripled. - The images are unreasonably dark, to where looking at jupiter only reveals a darkish brown, completely unfocused blob. - Ghosting and flaring of stars in extremely pronounced here. It flares so much that you cannot possibly focus onto any bright star. This eyepiece is plagued with severe problems when it comes to the quality of the glass inside. - The eyehole on this eyepiece is insanely small. It is nearly impossible for me to see anything with this eyepiece without accidentally hitting part of my head or face on the telescope. That is how small the eyehole is. =(I am completely clueless why zhummel would make this kind of eyepiece for a cheap starter kit. The customer base they are targeting would most likely never ever use the 6.3mm and definitely never use the 3.6mm. This is because cheaper telescopes with smaller apertures and slower focal ratios do not have as much of a highest useful magnification as a bigger aperture telescope like my lx90 8" sct does. 2x Barlow lens: This barlow seemed to work fine both with my meade 4000 SP, and the zhummel eyepieces. No complaints here. Filters: filters were fine although there was some gunk on some of my filters that i had to blow off with a duster. After having tested the entire set over 3 nights I was a bit dissapointed overall. I expected this eyepiece set to be better than my MEADE 4000 series super plossl 26mm. However, the set fell a bit short of that goal. The 32mm and 12.5gmm were not as sharp and didn't have as good color and resolution as my original meade 4000. The 6.3 and 3.6mm eyepieces are just completely useless. Noone will ever use them, not even people with 2000 dollar and higher priced telescopes like myself. The verdict: IF you have a telescope that is 8" in aperture or higher, I would not recommend this kit. You are much better off spending a bit more and getting eyepieces individually. It is better to have 1-3 eyepieces that you use frequently, than to have 20-30 of them lying around while only using a handful. If you have a smaller aperture scope, then these eyepieces will probably be all you need for a long long time. But then again, I am not sure why they included 3.6mm and 6.3mm eyepieces. For myself, I am a bit regretful of buying this set. As soon as I get a higher quality eyepiece, I probably wont use any of these eyepieces again. Also I will never ever be using the 3.6mm and 6.3mm eyepieces, as theyre just too poorly made to serve their purpose. The Barlow is fairly generic and I intend on buying a good quality meade/televue barlow very soon. All in all, I should have just bought a few good televue eyepieces instead, but hey good thing this kit is only [$] bucks. This entire kit ended up being worse than the original meade 4000 super plossl 26mm that came with the telescope. Live and learn. Perhaps this review will save someone with a good telescope, from making the same mistake i did.

This kit might be good for a beginner with a cheaper telescope but if you have a decent scope, they are really bad. Even with the 32mm, if you move your eye an 1/8" off center, you loose sight. It might be a good way to see what magnification that works with your scope
